VOLT is a smart USB Li-Polymer battery charger. It features power management circuitry with MCP73832, which can charge the battery over USB connector. Using provided screw terminals (VSYS and GND) VOLT can also be used to power your target device from battery (Vbat) or USB (5V). When USB is connected battery is charging and VSYS outputs 5V. Power LED is active when either USB or battery is connected, while Charge LED lights up only when battery is charging. Additional screw terminals with STAT and SENSE lines enable battery charge monitoring.
VOLT is ideal power source for devices that need reliable battery or USB power supply
Battery and MINI-B USB connectors are provided on-board. STAT line is open collector and must be pulled up to MCU power level for monitoring battery charging state. Charge and Power LEDs are provided for visual monitoring of board operation
SENSE line can be connected to ADC input for battery charge level monitoring. Board can be used for powering target device via provided VSYS and GND screw terminals
